Speedometer Off-Vehicle Inspection

Remove the speedometer from the meter assembly and
measure the resistance and the current consumption
between each terminal.

Speedometer Current Consumption

Note: 1. Use the analog type circuit tester.

2. Since the current consumption fluctuates when

the source voltage varies, check to be sure that
the voltage applied is 12V ± 1V.
